s claims. (c1. 22o-,61)V g This invention relates to a container in the nature of a can, pail or the like, which is constructed to be closed by a so-called slip-on cover, that is, a cover which has a skirt portion fitting around the top of the container body with a friction fit. The invention relates particularly to a container having a slip-on cover which is provided with an outwardly-extending flange at the lower part of the skirt and one object of the invention is toprovide a novel means for holding the cover to the container body which will prevent the cover from becoming loosened even if the lange of the cover receives blows or ishit by any object during transportation in such a way as Would tend to loosen the cover.

A further object of the invention is to provide a novel means for holding a cover of this type to a container which is constructed to facilitate the removal of the cover when it is desired to open the container. f f

In accordance with my invention the cover is held in closed relation by a cover-retaining ring which surrounds the container body and which is provided with a plurality of fingers that are bent over a peripheral ange with which the skirt of the cover is provided. The cover-retaining ring is readily disruptable at one point so that when the container is to be opened the ring is disrupted at said point and is then removable from the container body and cover after which the cover can be readily pried off from the container body.

In order to give an understanding of the invention I have illustrated inthe drawing a selected embodiment thereof which will now be described after which the novel features will be pointed out in the appended claims. 1'

Fig. 5 is a sectional viewon a reduced scale on the line 5 5, Fig. 2. Y

In the drawing, 1 indicates the body of a container which may be in the form of a `can or a pail or any other similar container, and 2 is the cover for closing the open end of the container. The container is shown asformed'with a bead 3 around its upper edge which'is formed by curling the edge of the container body inwardly and the -cover is ofthe slip-onf type, 'that is, it is provided with a skirt portion 4 adapted to embrace and have a frictional fit with the upper portion 5 of the container body. The cover is also shown as being formed with a bead-receiving groove 6 which receives the bead 3 of the container body 00 when the cover is applied and for making a` tight joint a layer of sealing compound 7 will be employed which lies between the bottom of the groove 6 and the bead 3. The cover is further provided with an annular outwardly-directed 05 flange 8 which is shown as situated at the lower edge of the skirt 4.

The cover 2 is retained in place on the containerbody by means of a closed cover-retaining ring which surrounds the container body adja- 10 cent the top and is held from upward movement and which is also provided with a plurality of fingers that are adapted to be bent over and embrace the flange 8. Said cover-retaining ring is shown at-Q and it is held from upward movement relative to the container body by engagement with a downwardly-facing annular shoulder 10 with which the container body is provided. This retaining' ring 9 underlies the shoulder 10 and embraces the portion l1 of the container 80 body directly below the shoulder, which portion has a smaller diameter than the portion 5 above the shoulder.

This cover-retaining ring is also provided with a plurality of fingers 12 which normally are di- 85 rected upwardly but which are adapted to be bent over the flange 8 of the cover as shown in Fig. 3.

The ring 9 is applied to the container body while the latter is being made and before the cover is sealed to the body and said ring 9 has 90 such shape that when it is placed around the body the upstanding fingers 12 will be spaced from the portion 5 of the container body a sumcient distance to receive the flange 8 so Vthat when the cover 2 is placed on the container body 95 as shown in Fig. 3, the flange 8 will pass down between the portion 5 of the body and the upstanding fingers 12. After the cover is in sealing relation to the container body then thesefngers 12 are bent over the flange as shown in full lines 100 Fig. 3 thereby locking the cover in place.

vIn the preferred embodiment of the invention the ring 9 is formed with the portion 13 which extends outward laterally and the fingers 12 rise from the outer edge of this portion 13.

The closed ring 9 is not permanently secured Ytothe can body but merely surroundsvthe canV body withv a more or less loose fit. Said ringis so made'rth'at it is readily 'disruptable at lsome Apointand the opening of the containerinvolves l10 the operation of breaking or disrupting the ring at its readily-disruptable point after which the ring can be readily removed from the container or will by its own resiliency spring off from the ange 8 thus permitting the cover to be removed.

One simple way of providing a cover-retaining ring which is thus readily disruptable at one point is to make the ring from a strip of metal of proper shape and of such a length thatv when the strip is placed around the container to form thenring the ends 14 and 15 of the strip will have an overlapping relation and then soldering these two overlapping ends together at some point as indicated at 16.

The portion 15 of the ring vat one end which overlaps the portion 14 is not provided with any fingers 12 and said portion 15 thus constitutes a tab which can be readily manipulated to disrupt the ring. yThis disrupting can 'be accomplished by grasping the end 15 of the ring with lpliers or some suitable tool and applying a pulling force thereon. A sharp Yjerkor quick force ap- ,pliedwill readily break thesoldered connection 'at '.16v thus disrupting the ring 9 and as this is done thering can be readily removed from the Ican withoutloosening the bent fingers 12 from the fiange. In fact, a natural resiliency of the :ring'may be sufficient so that when the ring is `.disrupted itwill spring off from the flange as show'n in dotted lines Fig. 5. 1 :As soon as the cover-retaining ring 9 has been thus removed then the cover 2 can be pried or Vforced off from the container body in any usual way. .Where the container is one which is formed withY a bead 17 below the portion 1l which is 'surrounded by the cover-retaining ring 9 then it may be possible tointroduce a tool between the beadof the container body and the flange 8 offthe cover and exert a prying force which will raise and loosen the cover so that it can be removed.

vThe construction of the cover-retaining ring 9 with the portion of considerable vertical dimension which encircles the portionY 11 ofthe container and the engagement of the ring with the yunder side of theshoulder 10 provides a construction Vwhich iswelladapted .to resist any force applied to the ange 8 of the cover tending to raise or loosen the cover. When a sealed container of this type is being shipped there is always the possibility that during transportation the lange 8 of the cover may receive a blow in a direction tending to lift or loosen the cover.

g With'the construction herein shown, however, the shape of the retaining ring and its engagement with the shoulder 10 of the body tend to resist any such force so that the container embodying this invention can be transported freely without danger that the cover will be loosened during transportation.

f. While .I have illustrated a selected embodiment -of the invention I do not wish to be limited to 4the constructional features shown.
